DSHD-300A Sea Engineering Geological Exploration Drilling Rig

  1. Application:   DSHD-300A sea engineering geological exploration drilling rig is a top drive power head type drilling machine with long feeding stroke. It adopts the advanced technique of regulating rotary speed with frequency changer and equipped with 12 m high derrick and heave compensator. It can be used to work under the condition of 100 m water depth and wind scale less than 5 grade. It also used for water area geological exploration drilling and pile hole drilling on river or lake. The main set of drill can be used for drilling pile holes in land.


  1. 1) Top drive power head of drill adopted frequency changer to adjust rotary speed steplessly. It features long feeding stroke, compact structure, rational arrangement and wide regulating speed range. With the result that drilling rig can meet the demand of drilling in a great variety of complicated formation2) Safety and reliable falling-resistant apparatus of top drive power head can ensure equipment and personal safety.3) Feed micro-adjusting mechanism of drilling rig can accomplish balanced drilling holes.4) Mechanization of breaking out drill rods with hydraulic break out apparatus reduces labor strength and increase drilling efficiency.5) Removing top drive power head rearward integrally ensures large floor space and convenient for frequently hoisting and lowering the drilling rod.6) Equipped with the advanced bottom sampling device, it can meet sampling demand in complicated formation.
  2. 1) Hole diameter Ø110 - Ø600 mm2) Hole depth 350 -60 m 3) Rod diameter Ø50 mm - Ø127 mm4) Rotary speed of top drive power head   Low speed range (forward and reverse) 7-233 r/min   High speed range (forward and reverse) 16-540 r/min5) Feeding stroke of top drive power head 3500 mm6) Electromotor power of top drive power head 30 kW7) Lifting capacity (single wire rope) of main hoist 30 kN   Lifting capacity (single wire rope) of auxiliary hoist 20 kN8) Derrick height 12 m    Derrick load 180 kN9) Mud pump BW-250 mud pump, BW-600 mud pump10) Hydraulic break out apparatus    Center hole diameter Ø450 mm   Breaking out diameter of rod or casing Ø50, Ø127, Ø178 mm   Breaking out torque 2.2 kNm11) Overall mounting dimension of main set   Length×Width×Height 2800×1500×5800 mm12) Weight 6500 kg
